I would look at using the nexec probe for this objective as I do believe that it supports scheduling and would not require additional configuration of tests. Also, if you need to capture any of the output, a nas LUA script can be created to execute the script via nexec probe callback [nimbus.request()], receive the output, and parse through and take actions, such as generating an alarm if there is something not right in the output from the script. Since the nas also supports scheduling/calendaring for executing scripts, you can control how often the nexec script is run from the nas configuration.
